Split it into 2-digit chunks, turn each chunk into its peg word, then link the peg images into one running story.

The peg list only goes to 99, so long numbers are handled by chunking:

1. Break the number into pairs from the left: 314159 → 31 · 41 · 59.
2. Recall each pair's peg: 31 = moth, 41 = rat, 59 = lip.
3. Link them into a single vivid, slightly absurd scene, in order: a giant moth with a rat riding it, nibbling a giant lip.

Recalling the story replays the pegs in sequence, and decoding each peg's consonants gives the digits back exactly. The sillier and more sensory the scene, the stickier it is.

Encode the lone digit with a single-digit peg (or pad with a leading zero) — don't leave it dangling.

Chunk from the left in pairs; the final odd digit becomes a one-sound peg:

• 12345 → 12 · 34 · 5 → tuna · mower · owl (5 = /l/).

Alternatively, some people pad a leading zero so everything pairs up (5 → 05 = "soil"), but keep one rule and stick to it so you never mis-split. The leftover is a real part of the number — dropping it silently loses a digit.
